Application June 4, 1946, Serial No. 674,320

2 Claims. (01. 126-410) This invention relates to improvements in oilheating stoves.

An object of the invention is to provide an improved oil heating stovewhich will include meansfor admitting air into a heating drum in saidstove to be heated therein, together with means for forcing the heatedair out through suitable ducts to be discharged through radiators in theseveral rooms of the structure in which the stove is located.

Another object of the invention is to provide an improved oil heatingstove which will include by said oil burner and forced through suitablydisposed ducts to be discharged in various places throughout thebuilding in which the stove is located.

A further object of the invention is to providevan improved air heatingoil stove which will include an oil burner'and an air heating'drum,together with means for admitting air to be heated to said drum at atangent thereto for forcing theheated air to oneor more outlets from theair heating drum and to ducts connected therewith extending to theseveral rooms to be heated.

Another object of the invention is to provide an improved oil heatingstove which will be highly efficient in operation, and relativelyinexpensive to manufacture and produce.

Other objects will appear as the description proceeds.

In the accompanying drawings which form a part of this application:

Figure 1 is a front elevation of the improved oil heating stove;

Figure 2 is a side elevation of the improved oil heating stove beingpartially broken away to show the air heating drum and connectionthereto;

Figure 3 is a vertical sectional view taken on the line 3-3 of Figure 4,and

Figure 4 is a transverse sectional view taken on the line 44 of Figure3.

Like characters of reference are used throughout the followingspecification and the accompanying drawings to designate correspondingparts.

In carrying out the invention, there is provided an improved oil heatingstove having an outer casing I preferably square in cross section formedwith a plurality of outlets 3 through its top 4, to be connected withsuitable ducts (not shown) to extend to various locations in thebuilding in which the stove is located.

A second casing or jacket 5 will be supported in spaced relation withinthe outer casing or jacket I in any desired manner, and will be providedwith a fire brick liner wall I in its lower end extending across thebottom of said casing or jacket 5 and up the side walls thereof aconsiderable distance. An oil burner 8 will be secured to the outercasing or jacket I adjacent its lower end, and will have its burner tube9 extending through the casings I and 5 and through the liner Ttodischarge its flame within said liner. Annular spaced rings III will beformed about the inner and upper end of the liner 1.

A series of spaced radially extending air inlet openings II will beformed through the casings or jackets I and 5 immediately above the topof the burner tube 9 to admit air from the outside to the inside of saidcasing or jacket 5. A cleanout door I2 will be provided through thecasing or jacket 5, and a smoke outlet I3 will be provided at its upperend to connect with the smoke pipe I4 leading to a suitable chimney (notshown).

An inner air heating drum I5 will be supported within the second casingor, jacket 5 in spaced relation thereto by means of the interconnectedwebs I5, and will be provided with the inlet connection I1 connectingwith the annular jacket I8 disposed about the upper end of the casing orjacket 5, and with the outlet connection I9 adjacent its lower endextending through the casings 5 and I to be connected to the ducts 20and 2| extending to suitable hot air outlets 22 and 23 locatedrespectively on the upper floor and in the same floor.

The sirocco type air blower 24 will be positioned on a bracket 25 on thecasing or jacket I and will be driven by an electric motor 26. A tubularair connection 2'! will extend from the blower 24 through the outer andsecond casings or jackets I and 5 and will be connected on a tangent at3I to the space between the annular jacket I8 and the air heating drumI5, whereby air under pressure will be blown through the connections orduct 21 to whirl about between the air heating drum I5 and the secondcasing or jacket 5 to enter said drum through its inlet H, to be heatedtherein, and to be forcibly discharged through the heated air dischargeoutlet I9 to pass through the ducts 29 and 2| to be discharged throughthe outlets 22 and 23.

A door 28 will be provided for the outer casing or jacket I, as clearlyshown in the drawings and will be provided with a suitable handle 29.

A port 30 will be formed through the outlet connection l9 to permit theheated air to pass upwardly between the casings and I to be dischargedthrough the hot air outlets 3 formed through the top 4 of the casing I.

From the foregoing description, it will be apparent that there has beenprovided a highly efficient form :of "oil heating stove-for buildings ofall types, which will be highly efficient in operation, and relativelyinexpensive to manufacture and produce.

While the preferred embodimentof the instant invention has beenillustrated,and idescr-ibedg it will be understood that it is notintendedto limit the scope of the invention thereto, as many minorchanges in detail of construction -may be resorted to withoutdeparting;frointhespirit of the invention.
